simplify 4pi*10^{-7}0.7

simplify

4 π \cdot 1 0^{- 7} 0.7

8.79646 E - 7

Solution steps

4 π 1 0^{- 7} \cdot 0.7

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

= 4 \cdot 0.7 π \frac{1}{1 0 ^{7}}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= 0.7 \cdot \frac{1 \cdot 4 π}{1 0 ^{7}}

\frac{1 \cdot 4 π}{1 0 ^{7}} = \frac{π}{2500000}

= 0.7 \cdot \frac{π}{2500000}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{π 0.7}{2500000}

Multiply the numbers:

3.14159 \dots \cdot 0.7 = 2.19911 \dots

= \frac{2.19911 \dots}{2500000}

Divide the numbers:

\frac{2.19911 \dots}{2500000} = 8.79646 E - 7

= 8.79646 E - 7
